Section 1: Data Collection Procedures
This document outlines attributes and data collection protocols for Common Stand Exams (CSE) and Inventory and Monitoring (IM), hereafter referred to as the R1 CSE/IM Field Guide.
In general, this document focuses on Common Stand Exams because stand exams are the most common protocols used for data collection, by a Forest. See R1 Supplement to National FSVeg/CSE User’s Guide Chapter 2: Preparation and Design for an overview of the steps to follow to prepare for, implement, clean, and load stand exam data.
Common Stand Exams generally are conducted on stands, a contiguous group of trees sufficiently uniform in size class distribution, composition, and structure, and growing on a site of sufficiently uniform quality, to be a distinguishable unit, such as mixed, pure, even-aged, and uneven-aged stands. A stand is the fundamental unit of silviculture reporting and record-keeping (FSM 2470.5). The polygon associated with the exam is delineated and maintained in FSVeg Spatial. It is expected that FSVeg Spatial stand delineations are reviewed and updated to represent the area over which the plots were selected and sampled, if needed, prior to data collection. Exams conducted on polygons that are not delineated stands in FSVeg Spatial need to be clearly identified as such by using a “P” in the location field (see Item 2.5, Setting Form) which results in a setting id that does not follow the standard stand naming convention used in R1. Contact the R1 field protocols specialist if further information or guidance is needed.
If information needs dictate that attributes will be remeasured over time, then the IM protocols and associated Exams software are used. These protocols allow additional attributes to be collected which assist with relocating plots and trees from measurement to measurement. It is critical for Forests considering implementing an inventory and subsequent monitoring project using IM protocols to contact the R1 Analysis Team with sufficient time for the Analysis Team to help with project design, protocols, and subsequent data analysis. Inventory plots remeasured over time require significant investment and good to ensure high quality data for analysis.
Protocols particular to IM are followed by (IM) in this manual and in the R1 CSE/IM Field Guide Supplemental Appendices. See the following table to find detailed information on IM specific attributes, Exams forms, templates and protocols.

As discussed in Section 1.2, there are three examination levels, Intensive Exam, Extensive Exam, and Quick Plot Exam. Data collection requirements and accuracy standards vary depending on examination level. The allowable range of measurement or classification error is termed the “tolerance”. Data item tolerance limits are indicated throughout this manual and in the R1 CSE/IM Field Guide Appendix T. The Exam Level indicates the minimum attributes collected. Information needs may dictate adding additional attributes, especially to the tree form.
1.1 Region 1 Required Fields

1.2 Exam Levels for the Tree Form
There are three examination levels: (3) Intensive Exam, (2) Extensive Exam, and (1) Quick Plot Exam. The Intensive Exam has the tightest tolerance standards, data collection requirements, and required accuracy. The Extensive Exam has less collection requirements and accuracy. Measurement tolerances, data collection requirements, and required accuracy for the Quick Plot Exam are relaxed to allow for rapid inventory procedure.
Data needs determine the examination level required. When data needs can be minimized and/or when data estimations and/or attribute groupings can provide acceptable levels of information, the Extensive Exam and Quick Plot Exam offer the greatest opportunity for cost savings. A major cost component for any exam is travel time and locating the stand and/or plots; therefore, it may be worthwhile to increase the exam intensity level so that a reliable, full characterization of the stand may be made now and in future analysis. In addition, if non-required fields are collected to supplement an Extensive Exam or Quick Plot Exam, the cost savings may be reduced to the point that there is little significant cost difference compared to an Intensive Exam. See the Setting Form, Item 2.13, for a list of the minimum attributes to collect by Exam Level of the Tree Form.
The reliability of an estimate is determined by how homogeneous the setting is and the number of plots that are measured. For a detailed discussion on determining the number of plots to install in order to meet the exams information needs, see R1 CSE/IM Field Guide Supplemental Appendix R1-A.
1.2.1 Intensive Tree Exam
An Intensive Exam is designed to have accurate tree measurements collected to tight tolerance standards. It provides a comprehensive inventory for stands. Trees on the large tree plot are recorded individually. Trees on the small plot may be recorded in groups, with the exception of growth sample trees. Diameters of live trees are measured to the nearest 0.1 inch. Tree heights are measured to the nearest foot. Growth sample trees (GST) are used to objectively select trees for additional measurements that are expensive to collect, such as radial or height growth, ages and heights. These measurements allow for relationships to be made base on the GST trees, so non-GST trees can have those attributes “dubbed in” during the compilation process. This provides a complete data set to meet reporting needs.
Barring any disturbances, this type of exam has the longest “shelf life” in FSVeg and is the best type of data to input into the Forest Vegetation Simulator (FVS). Intensive exams should have enough plots installed to provide an estimate that has a sampling error of 20% or less at the 90% confidence level for the primary attribute of interest (see 2.14, Exam Purpose).
Exam Purpose (SE or CI): When taking any level of examination that includes the Tree Data Form, and the EXAM PURPOSE (Item 2.14) is code “SE” or “CI” (Stand Exam or Stratified Random Sample / Compartment Inventory), all size classes of trees found in the stand must be sampled.
1.2.2 Extensive Tree Exam
An Extensive Exam is designed to have accurate tree measurements collected to tolerance standards tighter than a Quick Plot Exam, but not as tight as an Intensive Exam. Trees above 3.0-inches in diameter are recorded individually. Trees on the small tree plot may be recorded in groups. Some tree defect information is collected. No growth or age measurements are required. This limits the ability to assess old growth, to develop age class tables, and to calibrate growth functions in FVS. Extensive exams should have enough plots to provide an estimate for the primary attribute of interest (see 2.14, Exam Purpose), that has a sampling error of 20% or less at the 80% confidence level.
1.2.3 Quick Plot Tree Exam
The Quick Plot Exam is a rapid inventory procedure. Data needs determine the design of the Quick Plot Exam. Tree data may be grouped by species, diameters, heights, and/or damage classes on both the large and small plots. At a minimum, the Quick Plot Exam provides a statistically describable estimate of stocking by certain critical tree categories. Examinations may be custom designed in order to satisfy specific stand data needs for prescription development or for use as supplemental cruise plots. The selection of the Quick Plot Exam must be made on the basis of the type of stand to be evaluated and associated decisions that must be made. Quick plot exams should provide an estimate for the primary attribute of interest (see 2.14, Exam Purpose), that has a sampling error of 20% or less at the 68% confidence level.
1.3 Appendices
The CSE/IM appendices are the same as the National FSVeg/CSE User’s Guide appendices except:
• They only contain information pertinent to Region 1 procedures.
The Region 1 CSE/IM Supplemental Appendices have additional information/specifications for data collection in Region 1 that are not documented in the national appendices.
R1 Field Guide – CSE/IM Setting Form – Intensive/Extensive Section 2
Section 2: Setting Form - Intensive / Extensive Exam Levels The combination of Region, Proclaimed Forest, District, Location, Stand, Purpose Code, and Measurement Date fields uniquely identifies an exam associated with a setting.
The tolerance limits listed for items in this section are for the Intensive and Extensive examination levels. Attributes that don’t have a tolerance specified in this section should be defined at the project level, in the protocol or contract, based on project specifications. See Appendix T, Tolerances for Region 1 Common Stand Exam/Inventory and Monitoring, for a table of tolerances by form and attribute.
The examination level indicated on the Tree Data Form determines the examination level of the Setting Form.
2.1 Project Name (25-character) Required
Record the project name. Multiple settings may have the same project name. Special characters and periods (“.”) are not valid in project names and will cause the following pop-up error in FSVeg when trying to view the data.
❖ Tolerance (Project Name): No Errors
2.2 Proclaimed Region (2-digit) Required
Record “1” for Region 1.
❖ Tolerance (Proclaimed Region): No Errors
2.3 Proclaimed National Forest (2-digit) Required
Proclaimed Forest is the forest code that FSVeg currently has populated in the Proclaimed Forest field. Is used in the creation of the Setting Id in FSVeg and is part of linkage between exam data in FSVeg and the stand delineation in FSVeg Spatial.
The following Proclaimed* National Forest Codes are used in R1:
Forest # Forest Name Forest # Forest Name
02* Beaverhead-Deerlodge 11 Gallatin
03 Bitterroot 12 Helena
04* Idaho Panhandle 14* Kootenai
05 Clearwater 15 Lewis & Clark
08 Custer 16 Lolo
10 Flathead 17 Nez Perce
*Prior to migration to FSVeg, R1 used TSMRS and R1 Edit to manage stand information. Those databases did not discern between Administrative and Proclaimed Forest. Therefore, when migrating to FSVeg and FSVeg Spatial, both Administrative and Proclaimed National Forest were populated with the Forest number being used in 2000. So, Proclaimed Forest is not necessarily the congressionally mandated Forest number but the Forest number that is in FSVeg and FSVeg Spatial in the Proclaimed Forest field and was used by the Region in 2000, the date of data migration from the legacy database.
❖ Tolerance (Proclaimed National Forest): No Errors
In order to check the Proclaimed Forest associated with a stand in FSVeg Spatial, run the R01 Extract Vegetation Polygons record set writer in the Geospatial Interface. For more information see Geospatial Interface Content: FSVeg and FSVeg Spatial.
2.4 District (2-digit) Required
Record the 2-digit District code associated with the District. These District numbers should not be updated over time due to forest consolidation. They are the District numbers that were used when the Forest stand layer was migrated to FSVeg Spatial in 2010 based on the TSMRS District codes used in 2005. Refer to R1 CSE/IM Field Guide Appendix B for a list of District Codes.
❖ Tolerance (District): No Errors
In order to check the District associated with a stand in FSVeg Spatial, run the R01 Extract Vegetation Polygons record set writer in the Geospatial Interface, for more information see Geospatial Interface Content: FSVeg and FSVeg Spatial.
2.5 Location (16-character) Required
Record the Location (Compartment/Subcompartment) associated with the Proclaimed National Forest. These Location codes should not be updated, over time, due to forest consolidation. They are the Location codes that were used when the forest stand layer was migrated to FSVeg Spatial in 2010 based on the TSMRS District codes used in 2005.
In order to check the District, associated with a stand in FSVeg Spatial, run the R01 Extract Vegetation Polygons record set writer in the Geospatial Interface, for more information see Geospatial Interface Content: FSVeg and FSVeg Spatial.
In Region 1, Common Stand Exams are generally conducted on stands (see Section 1) whose associated polygon is delineated and managed in FSVeg Spatial. These exams should have a 4-character LOCATION code comprised of a 2-digit “compartment” code plus a 2-digit “subcompartment” code. This will yield a Setting ID in FSVeg of RR//FF//DD//CC//SS//TTTT (R=region, F= proclaimed forest, D=district, C=compartment, S=subcompartment, T=stand) and it will be named consistent with the stand polygons in FSVeg Spatial.
Exams conducted on polygons that are not coincident with delineated stands in FSVeg Spatial (see Section 1) need to be clearly identified as such by using a capitol “P” in the location field following the 2-digit “compartment” code and 2-digit “subcompartment” code. This will yield a setting id in FSVeg of RR//FF//DD//CC//SSP//TTTT.
❖ Tolerance (Location): No Errors

Code
Description
Photo Series Collect custom weight classes by down-wood diameter classes.
Note: This Exam Level is used when fuel loadings in a setting are not accurately represented by a single photo within in the photo series guide, ie various DWM size classes are associated with tons per acre taken from more than one photo. This method allows use of size class specific fuel loadings values from multiple photos within a fuel photo series guide.
This information is not translated into FVS or the R1 Stand Exam Summary Database.
See protocols in Down-Woody Material, Section 7, for detailed information.
• Collected using photo series guides, but recording tons per acre by fuels classes from different photos within the guide.
• Do Not use this Exam Level if assigning each plot to a specific photo, use the Residue Description Code on the Plot Form
• Do Not record values in the Residue Description Code in the Plot Form.
*If each plot is being assigned to a single photo, do not use this option. Set the down-woody material Exam Level to 0 and input phot information into Residue Description Code collected on the Plot Form (Item 4.13). See DWM Exam Level 0, below.
Not Collected or Not Collected on the Down-Woody Materials Form

2.14 Exam Purpose (2-character) Required
There are seven EXAM PURPOSE codes that are currently used in Region 1 associated with data collection: SE, CI, FI, RP, IM, LI or RE (codes described below).
The Exam Purpose codes identify the following aspects related to the sampling design and/or analysis capabilities of the data collected:
• Sample Accuracy (BA/TPA) – the reliability of the exam in estimating basal area, trees per acre, or the vegetation attribute of interest
• Sample Intensity (Tree) – the extent to which sample trees, representative of the entire population of size classes found in a stand/setting, have been included in the overall sample design.
• Sample Selection – the method used to select stands for measurement
• Sample Type – whether the exam is an intensification of the FIA grid or a polygon-based stand exam
Exam Purpose Codes
Name Description
SE Stand Exam General statistically valid stand exam
CI
Stratified Random Sample (Compartment Inventory)
Stands are selected for examination based on probability of selection proportional to size of stand
RP All other exams
Exams do not meet sample accuracy standards, or do not sample all trees in the stand, or the plots were not systematically sampled.
FI
FIA Midcycle Remeasure, R1 Intensified Grid
Work with R1 Analysis team if you plan to use this purpose code.
IM Inventory and Monitoring Plots are monumented and will be remeasured over time.
RE Stocking Surveys Used with R1 Stocking Survey Protocol.
LI Lidar training data Training data for lidar acquisition only.
See R1 Analysis Team if you plan to use this purpose code.
2.14.1 Exam Purpose Guidelines:
Use the guidelines and definitions listed below to determine which EXAM PURPOSE to select. Record the code that identifies the purpose selected.
1. Stand Exam (SE), or Stratified Random Sample (CI). A stand exam’s purpose is to collect reliable information on vegetation attributes.
Oftentimes, the primary attributes of interest are tree related, but not always.
An exam purpose of SE or CI must first meet criteria a, b, and c to ensure reliable information:
a. Sample Accuracy (BA/TPA) – A 20% Sampling Error at the:
• 90% Confidence Level was achieved for Intensive Exams (Tree data, Exam Level 3)
• 80% Confidence Level was achieved for Extensive Exams (Tree data, Exam Level 2)
• 68% Confidence level was achieved for Quick Plot Exams (Tree data, Exam Level 1)
• Common attributes of interest for accuracy levels include:
▪ Basal Area per acre (BA),
▪ Trees per acre (TPA) – trees per acre calculated on trees above breakpoint diameter (if the quadratic mean diameter is greater than breakpoint diameter), OR trees per acre based on the trees below breakpoint diameter (if the quadratic mean diameter is less than breakpoint diameter)
▪ Or the vegetation attributes of interest to meet information needs for the exam. For example, an old growth exam may have sample accuracy based on the trees per acre that are 9” dbh and larger.
The number of plots installed in the stand is related to the accuracy of the exam. It is understood that a 20% error may not always be achieved. However, an R1 FSVeg report will be provided which reports the error, at various confidence levels, for various attributes of interest. See the R1 Supplement to National FSVeg/CSE User’s Guide Chapter 2: Preparation and Design for additional information).
b. Sample Selection (Tree) – All live trees ≥ 1 foot tall, and all dead trees ≥ 3 inches diameter, are measured or tallied.
c. Plot Selection – The plots were systematically sampled with a random start or randomly located throughout the stand.
If all of the criteria listed above are true then use either:
SE - Stand Exam, to indicate that stand selection for sampling was dictated by local data needs.
CI – Stratified Random Sample (Compartment Inventory), to indicate that stand selection for sampling was based on random selection of stand polygons with probability proportion to size (acres) in the context of stratified random sampling or compartment inventory design. Forests that are using a stratified random sample which randomly selects stands should be working with the R1 Vegetation Analysis Team to ensure that data is collected and warehoused appropriately so it will be available for analysis.
2. Other Exam Purposes (RP). If any of the previous criteria are NOT met (e.g., an ocular macroplot is being collected, only down-woody fuel information is recorded, only snag information is collected, biased plot location), then the exam purpose code of RP – must be used.
3. Inventory and Monitoring (IM). This code is to be used for inventory and monitoring purposes where plots will be revisited and remeasured over time.
It is expected that Regional Protocols for installation and measuring over time will be followed. Work with the R1 Analysis Team when setting up this sampling scheme to ensure that trend data over time is available to meet monitoring needs.
4. Stocking Surveys (RE). This code is to be used with R1 stocking survey protocols, Common Stand Exam Protocols for Stocking Surveys.
5. Forest Inventory (FI). An exam purpose of FI indicates that the exam is a grid-based exam following protocols defined in the Region 1 Intensified Grid Field Procedures Using Inventory and Monitoring Protocols manual. This code indicates that data are not for base-level stand exam analysis, but are a spatially balanced sample of plots across a larger geographic area of interest. This code is also used for R1 projects that measure FIA grid plots between FIA measurements, such as measuring FIA grid plots after wildfire events and/or insect outbreaks. Contact the R1 Analysis Team to set-up sampling methods and protocols for these inventories.
6. Lidar (LI). This cold is used when collecting training data associated with
Lidar acquisition. Work with the R1 Analysis Team prior to using this Purpose Code to ensure that training data can be tied to Lidar data during analysis.
❖ Tolerance (Exam Purpose): No Errors
2.15 Stratum (6-character)
Record the current STRATUM for the setting area. Refer to aerial photo typing or other stratification information associated with the polygon. Forest direction dictates the list of strata definitions and codes used.
2.16 Existing Vegetation Reference (3-character) Generally not used in R1 Record the code identifying the reference used to obtain the dominant EXISTING VEGETATION COMPOSITION TYPE (Item 2.17) for the setting area. Refer to the R1 CSE/IM Field Guide Appendix E for a complete list of valid reference codes.
❖ Tolerance (Existing Vegetation Reference): No Errors
2.17 Existing Vegetation Composition Type (3-character) Generally not used in R1 Record the code for the current (not potential) vegetative or non-vegetative type dominating the setting area. Dominance is based on plurality of basal area. Refer to the R1 CSE/IM Field Guide Appendix E for a complete list of EXISTING VEGETATION COMPOSITION TYPE codes. Dominance type as per R1 Existing Vegetation Classification System (Barber and others, 2011), are calculated on all exam data loaded into FSVeg so collecting this attribute may not be needed.
2.18 Potential Vegetation Reference (3-character) Required
Record the code identifying the reference used to obtain the POTENTIAL VEGETATION (habitat type) for the setting area; refer to Item 2.19. Only one POTENTIAL VEGETATION REFERENCE code may be selected per examination.
Note: POTENTIAL VEGETATION REFERENCE 111 is used in stands that have potential vegetation codes from both Forest Habitat Types of Montana (Pfister, et al., 1977) and Forest Habitat Types of Northern Idaho: A Second Approximation (Cooper, et al., 1991).
Refer to the R1 CSE/IM Field Guide Appendix F for a list of potential vegetation references used in Region One and a list of what forest each reference can be used on.
This appendix includes non-forest references primarily used for special projects and intensified grid exams. If you are conducting timber based stand exams, you will likely be using 101, or 110.
❖ Tolerance (Potential Vegetation Reference): No Errors
2.19 Potential Vegetation (8-digit) Required
Record the code for the predominant POTENTIAL VEGETATION (habitat type) to phase for the setting area. Potential vegetation is the community that develops over time, primarily influenced by soil and climate. It represents the area in a climax or near-climax condition. POTENTIAL VEGETATION for the setting area is determined by the predominant POTENTIAL VEGETATION found in the stand. Refer to R1 CSE/IM Field Guide Appendix G for a complete list of POTENTIAL VEGETATION codes.
❖ Tolerance (Plot Potential Vegetation): Accurate to R1 Habitat Type Group. See
Table 2 in R1 Forested Potential Vegetation Group Crosswalk, Region 1 Existing and Potential Vegetation Groupings used for Broad-level Analysis and Monitoring (Milburn et al. 2015) unless specified otherwise for the project.
2.20 Structure (2-character)
Record one of the following codes that best describes the overall structure of the setting. STRUCTURE describes the distribution of tree-size classes within the stand.
Note: Vertical structure is calculated as per R1 Existing Vegetation Classification System (Barber and others, 2011) for all inventory data so this attribute does not need to be recorded on all exam data loaded into FSVeg. Collecting this attribute may not be needed.
SS
Single story - A single even canopy characterizes the setting. The greatest number of trees are in a height class (or diameter class) represented by the average height class (or diameter class) of the setting; there are substantially fewer trees in height/diameter classes above and below this mean.
TS
Two-storied - Two relatively even canopy levels can be recognized in the setting. The frequency distribution of trees by height class (or diameter class) tends to be bimodal. Understory or overtopped trees are common. Neither canopy level is necessarily continuous or closed, but both canopy levels tend to be distributed across a predominance of the setting (e.g., overstory with regenerated understory).
MS
Multi-storied - At least three height-size classes are commonly represented in the setting. In general, the canopy is broken and uneven although multiple canopy levels may be distinguishable. The various size classes tend to be uniformly distributed throughout the setting.
MO
Mosaic - At least two distinct height size classes are represented; these classes are not uniformly distributed, but are grouped in small repeating aggregations, or occur as stringers less than two chains wide, throughout the setting. Each size class aggregation is too small to be recognized and mapped as an individual setting.
UA
Unknown/un-assessable - A structure classification was attempted, but the stand did not fit into one of the pre-defined categories. Note in the remarks column the reason the stand could not be classified.
2.21 Setting Capable Growing Area (3-digit) Required
Estimate the percent of the setting area capable of supporting trees. Make deductions for areas such as roads, creeks, swamps, rock outcrops, etc. For example, if an area contains 5% rock outcropping and 10% road, record 85% for SETTING CAPABLE
GROWING AREA.
❖ Tolerance (Setting Capable Growing Area): ± 10 percent
2.22 Setting Fuel Model (2-digit)
Record the predominant fuel model for the setting determined by the predominant Fuel Model in the stand, refer to PLOT FUEL MODEL (Item 4.12). See the R1 CSE/IM Field Guide Appendix U for Fuel Model codes. It is highly recommended that individuals collecting this data first obtain the appropriate training.
Note: If FUEL MODEL data are the only fuels related information collected (e.g., it is collected instead of Brown’s Protocols), record “0” for EXAMINATION LEVEL (Item 2.13) on the Down-Woody Materials Form.
This information is translated into FVS if collected.
2.23 Setting Elevation (5-digit) Required
Record the predominant setting elevation, to the nearest foot.
❖ Tolerance (Setting Elevation): ± 100 feet
2.24 Setting Aspect (3-digit) Required
Record the average or predominant aspect for the setting area (to the nearest degree, 0° to 360°). Setting aspect is the general direction toward which the setting faces.
Setting aspect may be determined from contour maps or by taking compass readings directly down slope at various places within the setting.
SETTING ASPECT coding guidelines:
• If aspect changes gradually across the setting, record an average aspect.
• If aspect changes across the setting, but is predominately of one direction, code predominate direction, rather than the average.
• If the setting falls on or straddles a canyon bottom or narrow ridge top, code the aspect of the ridgeline or canyon bottom.
• If the setting falls on a canyon bottom or on a narrow ridge top, but most of the area lies on one side hill, code the aspect of the side hill.
Examples:
Aspect Code Description
0 Flat
183 183°
360 360°
999 Indeterminate/No predominant aspect/Undulating
❖ Tolerance (Setting Aspect): ± 45 degrees
2.25 Setting Slope (3-digit) Required
Record the average or predominant slope for the setting area (to the nearest 1 percent).
SETTING SLOPE coding guidelines:
• If slope changes gradually across the setting, record an average slope.
• If slope changes across the setting, but the slope is predominately of one direction, code the predominant slope percentage rather than the average.
• If the setting falls directly between two side hills, code the average slope of the side hill(s).
• If the setting falls on a canyon bottom or on a narrow ridge top, but most of the area lies on one side hill, code the slope of the side hill.
❖ Tolerance (Setting Slope): ± 10 percent
2.26 Setting Slope Position (2-character)
Record the position of the setting on the landscape as defined below. Slope position definitions from: National Soil Survey Handbook (Title 430-VI). 1993. USDA Soil Conservation Service.
SU
Summit/Ridgetop/Plateau. The topographically highest hillslope position of a hillslope profile and exhibiting a nearly level surface.
SH
Shoulder. The hillslope position that forms the uppermost inclined surface near the top of a hillslope. It comprises the transition zone from backslope to summit.
BS
Backslope. The hillslope position that forms the steepest inclined surface and principle element of many hillslopes. In profile, backslopes are commonly steep, linear, and bounded by a convex shoulder above and descending to concave footslope. They may or may not include cliff segments. Backslopes are commonly erosional forms produced by mass movement and running water.
FS
Footslope. The hillslope position that forms the inner, gently inclined surface at the base of a hillslope. In profile, footslopes are commonly concave. It is a transition zone between upslope sites of erosion and transport.
TS
Toeslope. The hillslope position that forms the gently inclined surface at the base of a hillslope.
